AUTOMATIC ROTARY BOOK DISPLAY.

Application filed. December 11, 1925. Serial No. 74,770.

This invention relates generally to advertising devices, the inventionhaving more particular reference to a novel type of advertising device.

The invention has for an object the provision of an improved advertisingdevicein which cards having advertising or display matter may be exposedto View one after the other.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the follow ing descriptionand accompanying drawings,

and to the appended claims inwhich the va.

rious novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a top plan view of my improved advertisingdevice.

Fig. 2 of the drawings is a front view thereof.

Fig. 3 of the drawings is a side view thereof. 7

Fig. 4 of the drawings is a front. perspective view of my improveddevice showing the working parts enclosed by a case or cover.

Fig. 5 of the drawings is a sectional View taken on the line 5-5 ofFigure 6.

F ig. 6 of the drawings is an enlarged fragmentary detail view of myimproved device.

Fig. 7 of the drawings is a front view of a modification of my improveddevice.

Fig. 8 of the drawings is a side view thereof. V

Fig. 9 of the drawings is an enlarged fragmentary detail view.

Fig. 10 is a similar view of a detail thereof.

My improved advertising device comprises a plurality of cards 10 havingadver tising or'display matter printed thereon.

The cards 10 areattached to the upper clips 11 and the lower clips 11,said clips being .held by connecting strips 11 which have.

apertures located therein to accommodate the rings 12. -The gear isattached at or near the upper rotatively The finger 30 having a verticalextremity 30 is jointed to the arm 65. by means of the spring 66, so asto afford a certain amount of flexibility. The arm is pivotally at- Thecollar 66 is attached to the vertical shaft 61.

As a means of operating the said finger 30, I have provided an electricmotor 31 connected to any suitable source of power, and

extremity of the vertical shaft '61,

mounted in suitable bearings.

The shaft 44 is rotatively mounted in suitable bearings 45 and 46 andhas slidably at "tached thereto a friction wheel 47 so located as tomake contact with the periphery of the cone 41. The friction wheel 47 isprovided with a grooved portion 48 to accommodate the fork 49 of thelever 50 which is pivoted as at 51 and has attached thereto a suitableand conveniently located handle 52, as a means of sliding the frictionwheel 47 along the cone 41in order to vary the speed. of the shaft 44.As a means of holding the friction wheel 47 in any desired relativeposition, I have provided a sector 53 having notches 54 or protrudingportions to engage the handle 52.

The intermittent gear 55 is attached to the shaft 56 and meshes with arack 57 cut or otherwise formed on the shaft 56 which is a slidable fitin the bearing 58 and has cut or otherwise formed thereon a second rack59 meshing with the gear 60 which .is attached to the vertical. shaft61. The heretobefore described construction being such as will move thefinger from the position as designated by the numeral 62, to theposition designated by the numeral 63 Fig. 1. As a. means tive frame,such as designated by the. nu-

meral 68, have a top 69, to support the heretobefore described workingparts,and a base 70, it being further understood that the top 69 andbase 7 0 may be of any suitable attrac-.

tive shape or design.

As a means of enclosing the hereinbefore descrlbed working parts, I haveprovided a suitable cover 71, having an elongated slot I 72 toaccommodate the finger 30, so as to permit of the movement thereof, andan elongated aperture 73, to accommodate the handle 52 which protrudestherefrom. The cover has suitable identification marks 74 to designatethe speed of the friction wheel.

-- and a tapered extremityv 82 sollocated' astoforcethe Sfl-lCl finger30. downward so as to; cause thevertical extremity 80: to engage Theidentification marks 74k are adjacent to the handle which protrudes fromthe cover.

Referring in particular to Figures 7 and 8 showing a modification of myimproved advertising device, in order to accommodate cards of varioussizes, it is. necessary to provide a means of extending the framemembers 75 in a vertical and horizontalposition. For this purpose, theframe members 75' are of; telescopic construction and are attached toone another by means of wing; nutsTG: conveniently located in slots 77:.1

I have aboue described the movement. of the finger. 30,. and it will befurther understood that the upper clips 11 are provided. with a;protruding portion 78 located at the rear. ofiea'cln of the said cardsand, extending; slightly above the top edge of the said cards. Itwill bealso understood that the cam member 79 is-suitably attached to the top69,. andhas an upright portion. 80, with an elongated slot 81 to engagethe arm 65,

between the card designated by thenumeral 83, Figurel, and theprotruding portion 78-, designated by thenumeral 84, Figure The cammember? 9 has also'a second up right port-ion 85. with an. elongatedslot 86 to engage the finger 30, and a tapered extremity 8.71 todisengage the; vertical. extremity 30 from between the card designatedby the; numeral; 83, and theprotruding portion 7:8, designated by'thenumeral 84, when thevert-ical extremity 31 hasrmoved the card 10,designated. by the numeral 83, to: the position. designated by.thenumeralSS.

It is'obvious that I haveprovided a means ofexposing, to view a.plurality-ofcardsliaving advertising or displayotherwise placedthereomone afterthe other;

While I: have above described the prefenred' form, construction: and:arrangement oftheseverali elementsemployed, it will be understood thatthe device is nevertheless, susceptible of considerable of resorting toall such. changes as may be fairly embodied within the spirit and? scopeofs the invention. as claimed.
